About OZO
Simple, fast, useful tools for your business, free for everyone
OZO makes the small, repetitive jobs of running a business or a household quicker, without signups, trials or paywalls.
Why OZO exists
Small jobs shouldn't need big software. Sending an invoice, writing up an estimate or working out a number should take a couple of minutes, not a free trial, a signup form and a credit card.
OZO is a growing collection of simple online tools for your business. Each one does a single job well, opens instantly in your browser and is free to use.
What we believe
Free means free. There is no premium plan, no feature that disappears after a trial and no "download for $9.99" at the last step. You can create, customise and download your documents without paying anything.
No signup to get started. Every tool works without an account or any signup: open it, use it and download the result.
Your work is yours. Your drafts stay in your own browser, and PDFs are made on your device. We don't sell personal data. The details are in our Privacy Policy.
Works everywhere. OZO is designed for phones first and works just as well on a tablet or a large screen. You can install it like an app and keep editing drafts offline.
How OZO stays free
OZO is funded in two ways:
- Ads shown around the tools. They are never placed inside your documents, your PDFs or the emails you send,.
- Donations from people who find OZO useful. If a tool saved you time, you can buy us a coffee.
That's the whole business model. It lets us keep every tool open to everyone.
What's next
OZO now covers the business documents small businesses send most, from quotes and invoices to receipts, purchase orders and account statements, plus a growing set of calculators such as the profit margin calculator, VAT calculator and loan calculator. Makers and file tools come next. Everything that's live is on the tools page.
